Intracoastal Homes for Sale in Palm Beach: Read the Bridges First

Before you fall for the dock, check what sits between it and the inlet.

Short answer

If you're buying an Intracoastal home in Palm Beach County for a boat, the bridges and the channel matter as much as the dock. The federal channel south of Fort Pierce is authorized at 10 feet deep, the drawbridges around the island open on a set schedule, and some bridges are fixed. Map the route from the dock to the inlet with your boat's air draft and draft in hand.

The house is the easy part

When people tour Intracoastal homes for sale in Palm Beach, they look at the dock, the lift, the seawall and the sunset. All worth looking at. But if the whole point is the boat, the more important stuff is out of sight: how deep the water is between your dock and the channel, how many bridges sit between you and the inlet, and whether those bridges open when you want to go fishing or only on their own schedule.

Two houses with the same dock can be very different boating homes. One is a short run to open water. The other means waiting on a drawbridge every trip, or never fitting under a fixed span at all. Mapping that out takes an evening with a chart and a few federal documents, and it can save you from buying the wrong house.

The channel: 10 feet, on paper

The Atlantic Intracoastal Waterway through Palm Beach County is a federal channel. The U.S. Army Corps of Engineers says the stretch from Fort Pierce to Miami is authorized at 10 feet deep, and NOAA's Coast Pilot gives the same project depth, 10 feet to Miami.

Two things to keep in mind. First, "authorized" is the design depth, not a promise about what's under your keel on a given day. Shoaling happens, and the Corps dredges on its own timeline. Second, the federal channel isn't your dock. The water along your seawall, across the flats and in any side channel or canal that leads to the ICW can be a lot shallower. Before you fall for a house, get a depth reading at the dock at low tide and ask a local captain or marine surveyor about the route out. Our deepwater estate guide and the deepwater homes page cover what "deepwater" usually means here.

The bridges: clearance and schedule

Here's where Lake Worth gets interesting. The two bridges between West Palm Beach and the island are both bascule drawbridges, and both run on a schedule set by the Coast Guard in federal rules (33 CFR 117.261):

• Flagler Memorial Bridge (State Route A1A), mile 1021.8. Vertical clearance of 24 feet at mean high water when closed. It opens on the quarter and three-quarter hour, except on weekdays from 7:30 to 9 a.m. and 4 to 6 p.m., when it only has to open on the quarter hour.
• Royal Park Bridge (State Route 704), mile 1022.6. Vertical clearance of 21 feet at mean high water when closed. It opens on the hour and half hour, except in those same weekday windows, when it only has to open on the half hour.

The Coast Guard set those weekday rush windows in a 2025 rule published in the Federal Register, so if you've boated here for years, it's worth rereading the current schedule rather than trusting memory.

North of there, toward the Palm Beach Gardens and Jupiter side, the schedules keep going. The Parker Bridge (US 1) at mile 1013.7 opens on the quarter and three-quarter hour. The PGA Boulevard Bridge at mile 1012.6 and the Indiantown Road Bridge at mile 1006.2 open on the hour and half hour. The Blue Heron Boulevard bridge in Riviera Beach is a fixed span, so the question there is simply whether you fit.

What that means for a house hunt

Put the house on the chart, then trace your route to the inlet you'd actually use. A house south of the Royal Park Bridge heading out the Palm Beach Inlet passes under Royal Park and then Flagler Memorial. (NOAA's Coast Pilot calls that inlet Lake Worth Inlet; most locals just say the Palm Beach Inlet.) If your boat can't clear 21 feet closed, that trip runs on the bridge schedule both ways, every time. Miss an opening and you wait.

For a center console with a T-top that clears easily, none of this may matter much. For a sportfish with a tower, a sailboat, or a yacht with a radar arch and antennas, it can decide the house. Know your real air draft, with everything up, and your draft fully loaded. Then compare that with every bridge and every shallow spot between the dock and open water.

It's also why Intracoastal homes in different parts of the county feel so different to boaters. Inlet proximity in Jupiter, the canals of North Palm Beach, and the bridges and inlets farther south all set up the trip differently. The area guides walk through each one.

How I'd tour a house as a boater

If you can, see the house from the water before you see it from the driveway. Run the route from the dock to the inlet in a boat about the size of yours, ideally near low tide, and time it. Note every bridge, every no-wake stretch and every spot where the depth sounder makes you nervous. That one trip tells you more than a stack of listing photos.

Then look at the dock with your boat in mind, not the seller's. Is the lift rated for your boat? Is there room to turn around, or will you be backing out of a tight canal every time? Which way does the wind usually push you while docking? Ask the neighbors, too. People on the water love talking about the water, and they'll tell you which bridge tender is quick and where the shoals tend to build up after a storm.

Last thing: talk to your insurance agent and, if you have one, your captain before you're under contract. The boat and the house get insured separately, and both can be affected by where the dock sits and how exposed it is. Better to know that during the inspection period than at closing.

A quick pre-offer checklist for boaters

• Your boat's air draft (with antennas, outriggers and arch up) and loaded draft, written down
• Depth at the dock and along the route to the ICW, measured at low tide
• Every bridge between the dock and your inlet, its clearance and its schedule under 33 CFR 117.261
• Whether any of those bridges is fixed
• Seawall, dock and lift condition and permit history (see our seawalls and docks guide)
• Insurance quotes from a licensed agent before you're under contract

Ocean or Intracoastal?

If you're still deciding between the beach and the lake, our Intracoastal vs. oceanfront guide lays out the trade-offs, and the rest of the waterfront guides cover buying, selling and the main waterfront areas of Palm Beach County.

I'm Zachary Vorsteg, a Florida-licensed real estate sales associate with Cornerstone Realty, and I help buyers and sellers with waterfront homes across the county. You can see how I run the rest of my business at zacharyvorsteg.com. When you have a boat in mind, or already own one, send its length, air draft and draft through the inquiry form, and I'll start the search from the water side instead of the listing photos.

This guide is general information, not navigation, legal, insurance or financial advice. Bridge schedules, channel conditions and rules change. Always check current Coast Guard notices, NOAA charts and the Coast Pilot, and rely on a qualified captain or surveyor for your boat.
